Vector texture not rendering in EEVEE but showing in viewport
i just could &quot;work&quot; now with your blend file, which is just a cube with emission color.
I got this as result: 

you can get this effect by adding a particle system to your object.

set your particle settings like this:




create a small icosphere with material -&gt; emission color: pink, emission strength: 7 or more

use this icosphere in you particle settings as render object
